  Abstract

Vehicle-to-vehicle (V2V) communication was developed primarily for exchanging messages that enhance safety and traffic efficiency. It enables ITS applications—such as platooning, traffic-signal optimization, and flow control—and complements sensor-based autonomous driving. 3GPP has standardized V2V from Release 14 through Release 18. In platooning, operations occur mostly on highways or in non-urban areas and use groupcast among members, yet limited multipath can leave some non-line-of-sight vehicles nearly disconnected. Direct V2V reliability can therefore degrade. This paper proposes leveraging vehicle-to-network-to-vehicle (V2N2V) as an additional path to improve packet delivery ratio (PDR), enabled by the growing deployment of connected vehicles. We design a signaling procedure that activates dual-path use on each vehicle without introducing new messages or requiring 3GPP changes. To curb the higher latency of the V2N2V path, we propose an IP-address-based breakout at the gNB. Using the ns-3 5G-LENA module, we implement and validate the design, demonstrating significant gains in information-update timeliness and PDR compared with V2V alone.
